Openstack Designate
OpenStack Designate Stephan Lagerholm Graham Hayes What is OpenStack? OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through RESTful web services. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2012, it was managed by the OpenStack Foundation (Source: Wikipedia) 2 Designate • Designate started as a project to maintain DNS infrastructure for OpenStack Users. It was an ecosystem project that was in production at both HP’s and Rackspace’s clouds. During 2015, Designate was moved into OpenStack Foundation and in 2017 it became a registered trademark. • Designate is providing API, CLI and a Graphical User interface so that OpenStack Users can setup and make changes to DNS data. The zones are thereafter exposed to secondary DNS servers via Zone Transfers. • Officially Bind 9.X and PowerDNS 4.X is supported although other DNS servers are known to work too. Most resource Record Types such as A, AAAA, PTR, CNAME, NS, MX, etc are supported 3 Producer Producer Backend Producer Producer Producer Worker Customer Facing API Central DNS Servers Standard XFR Secured by TSIG Nova / DB Mini -
Based Services Using XRI-Based Apis for Enabling New E-Business
International Journal of E-Business Development May. 2013, Vol. 3 Iss. 2, PP. 64-74 An Approach for the Composition of Generic Cloud- Based Services Using XRI-Based APIs for Enabling New E-Business Antonio Celesti1, Francesco Tusa2, Massimo Villari3, Antonio Puliafito4 DICIEAMA, Università degli Studi di Messina Contrada Di Dio, S. Agata 98166, Messina, Italia [email protected]; [email protected]; [email protected]; [email protected] Abstract-Nowadays, cloud computing offers more and more business opportunities, and thanks to the concept of virtualization, different types of cost-effective Cloud-based services have been rising. Virtualization of computing, storage, and networking resources, and their interconnection is at the heart of cloud computing, hence enabling new E-Business scenarios. In such a context, APIs for enabling Cloud-based services are strongly required, nevertheless, methods, mechanisms and tools for exploiting virtualized resources and their utilization for developing anything as a service (*aaS) are still ad-hoc and/or proprietary in nature. In this paper, we discuss how to use an adaptive standard protocol, i.e., XRI, for enabling cloud service providers to arrange their own Cloud- based services, building them on top of the IaaS provided by other service providers. Keywords- Cloud Computing; Cloud Management; Federation; Service Composition; E-Business I. INTRODUCTION Today, cloud computing represents a tempting business opportunity for ICT operators of increasing their revenues [1,2]. The cloud ecosystem begins to be clearer and the role played by cloud service providers appears more defined than the past. Moreover, the number of new public, private, and hybrid clouds rising all over the world is continually growing [3]. -

Eucalyptus - Installation Manual
Eucalyptus - Installation Manual Hannes Gamper and Tomi Pievil¨ainen December 3, 2009, Espoo Contents 1 Introduction 1 2 Requirements 1 3 Installation procedure 2 3.1 Install Ubuntu 9.10 Server edition and Ubuntu Enterprise Cloud . 2 3.2 Step 1 - Prerequisites . 2 3.3 Step 2 - System Installation and Configuration . 2 3.4 Step 3 - Registering UEC Components . 3 3.5 Step 4 - Initial Login . 3 1 Introduction Cloud computing systems provide users with access to large amounts of computational resources and data [4]. Virtualisation is used to hide information like physical location and architectural details of the resources from the user. Eucalyptus is an open-source software framework for cloud computing implementing Infrastructure as a Service (IaaS). It is tailored for the use in the research community. Users can run and control virtual machine instances on a variety of physical resources found within academic settings. 2 Requirements Eucalyptus can be installed via the Ubuntu Enterprise Cloud, introduced in Ubuntu 9.04 [3]. The following installation instructions are based on Ubuntu 9.10 Server edition. In terms of hardware requirements recommended minimum specification is a a dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. 1 3 Installation procedure • Ubuntu 9.10, server edition • dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. • port 22 needs to be open for admins (for maintenance) • port 8443 needs to be open for users for controlling and sending requests to the cloud via a web interface 3 Installation procedure The installation instructions in this manual closely follow those given on the \Ubuntu Enterprise Cloud" homepage [2], with some remarks regarding installation from scratch via the Ubuntu 9.10 server edition. -
A Survey of Collaborative Tools in Software Development
1 INTRODUCTION A Survey of Collaborative Tools in Software Development Anita Sarma Institute for Software Research Donald Bren School of Information and Computer Sciences University of California, Irvine [email protected] ISR Technical Report # UCI-ISR-05-3 March 22, 2005 1 Introduction Collaboration is at the heart of software development. Virtually all software devel- opment requires collaboration among developers within and outside their project teams, to achieve a common objective. It has in fact been shown that about 70% of a software engineer’s time is spent on collaborative activities [219]. Indeed, col- laboration in software development has been studied by researchers in the fields of Software Engineering and Computer Supported Cooperative Work (CSCW) since the 1980s and has produced a wide range of collaborative tools. Enabling software developers to collaborate effectively and effortlessly is a difficult task. The collaboration needs of the team depend to a large extent on environmental factors such as, the organizational structure of the team, the domain for which the software is produced, the product structure, and individual team members. Accordingly, research in collaborative development has produced a host of tools, each typically focussing on a different aspect of collaboration. Most teams have their favorite repertoire of tools that has been built from historical use. These tools may not always be the best suited for the team, but the team still uses them nevertheless as the inertia and cost of trying out new tools surpasses the benefits. A number of classification frameworks exist that can be used to classify collaborative tools. In addition to placing the various tools in context, developers can use these frameworks to select the right mix of tools fit for their needs. -
